Welcome to BAFM#
This blog is a collection of thoughts, experiences, and technical insights from a sysadmin’s perspective. Here you’ll find posts about system administration, infrastructure challenges, troubleshooting adventures, and the occasional philosophical rambling about technology and its role in our daily work.
Whether you’re a fellow sysadmin looking for solutions, someone curious about the behind-the-scenes work that keeps systems running, or just stumbled upon this corner of the internet – welcome! Feel free to explore, and don’t hesitate to reach out if you have questions or want to share your own experiences.
Follow me through my journey through life with all it’s neat little tricks, caveats and side-quests.

Well, it’s been quite a while since most of the people last heard a word from me. The last few months I’ve been extremely busy with work-related tasks (and as a side-effect of that, didn’t want to spend much time in front of the computer after 9 hours of work). I also started spending more and more time in the gym, like nearly two hours every Tuesday and Thursday.
I finally fixed our replication issues, we do now have a working! MySQL Multi-Master ( 1. Node, 2. Node -- bear in mind, this boxes are only serving MySQL and nothing else, so don’t use these configurations on mixed setups) Replication Setup as database back end for our TYPO3-vHosts. all the web nodes are now serving the content from a clustered, shared SAN volume (is that a good thing ? 😛 - don’t know yet …) our VI environment is getting more and more acceptance (even if you hear some complaints now and then, like “awww, damn that crap my 4GiB RAM, 2x3.0GHz Windows 2008 is running soooo choppy” - simple answer, don’t use Windows Server 2008 and/or Windows Vista!) I finished prepping our VM templates (at least the Windows ones) we’re still putting together the plans on whether or not invest into a VDI solution. The next few weeks are gonna be as frantic as the weeks before, I still have to migrate a lot of TYPO3 installations to our new cluster (which sadly needs time, as we need to wait for DNS changes to propagate). Honestly, I might be ending up extending the SAN volume for the MySQL data storage, as even with only three somewhat busy sites, the binary log of the last 5 days is about 2GiB in size. And we still have ~ 20 other busy sites on a separate box.

I just found a rather oldish picture of myself. The date says it’s from last year ( Fri Feb 9 22:33:06 2007 to be exact) …
Me with beard! (Or: WHO THE HELL IS THIS ?)
One year later, I can’t imagine having such a beard ever again …
Well, as it is Saturday and I’m having lots of time (whereas I’d usually spend it working), I thought I’d give Windows Server 2008 a try. What interested me most, is the Windows Server 2008 " Server Core Installations", as it’s supposed to lower the security risk (as there is no Internet Explorer, no Explorer nothing running by default, only a simply cmd.exe).
As one of my co-workers requested me to upload the Standard/Enterprise/Datacenter DVD (which he got through our Microsoft Select 6.0(?) agreement) to our ISO’ VMFS, I had the DVD already at hand. As for that, I really love the feature set of VMware.

Well, apparently some people don’t have any value for other people’s property. It’s that way in big cities, but apparently it’s the same is this shitty, lil’ village.
Scratch, top view
Scratch, side view
Whoever did that had serious fun with a key or something else. Tough, if I ever gonna get that person, I’m gonna rip his arse apart. The painters tell me, I do have to expect to pay ~300 EUR, as to the scratch being up to the primer below the upper color layer. So they’ll either have to paint half the door, or the whole door which really pisses me off!
I’ve been looking for this over and over and over, until I had some inspiration today (thanks to Andew and Chris) .. this has one and only one sole purpose: safekeeping, so I don’t end up searching for it all over again …
To free pagecache:

After blogging the last time about the PacketPro 450 LoadBalancer appliance, the guys over at teamix seem to have taken that to heart and implemented a rather nifty thing for their new release.
It’s called " Port forwarding", which is basically what you’d figure from the name. It bounces ports around the load balancer, but saves you from creating a separate virtual server (and adding the physical servers to that one), but also saves you from modifying the syslog-ng configuration on the balanced servers.
Ok, so after my first day yesterday after a rather long vacation I today wanted to look at the problem that the Administrator password isn’t changed when using VirtulCenter’s clone customization functionality (which relies at least for Windows on sysprep).
After a short googling, I stumbled upon this.
Simple problem short … Don’t specify an Administrator password for the template. Then you should be able to change the Administrator password when cloning the template. It’s " should", as the VM’s are still updating.

Well, it’s yet again New Year’s Eve. Yet again a whole year passed by blazing fast, I didn’t manage to get everything done like I wanted.
That includes the following things:
getting a better job (and probably better paid too!) getting a better life (well, it’s as it sounds like - my current life is rather unhealthy, and thanks to a friend I got the grip onto myself and started changing a few things - like doing a small workout every day, a bit more movement all over the day and so forth) Which also means I do have some resolutions for the next year …

Actually there’s nothing to see here. It’s just to get it somewhere more obvious then my irc logs …

Well, some of you know I’m a bit clumsy. Ok, I went buying some stuff for Saint Nicholas for the ones I love, which came to me about ten minutes before the shops are closing. Navigated my butt into the car, drove the ~6km to the nearest store (which still had open, that was around 20:00).
Got all I wanted, went back to my car (you know, this one) this and put the stuff into the trunk. When closing the trunk, I felt some opposition, so I closed it a bit harder. “Closed” I thought to myself and went back into my car. When turning on the ignition the onbord computer suddenly complained “trunk open”, so I went back out, trying to open the trunk. WTF .. I couldn’t get it open. So I tried again, still nothing.
